Very cool... but i made two tweaks, one is a
simplified version of Rudif's default suggestion,
and the other
changes the text to something more triangle-ish (i don't
think it significantly reduces the obfuscation)

Here is an alternative solution.
This one is a little shorter and strict and warning safe.
Also it does not emit an empty first line.
I developed it from ideas in previous solutions posted to fwp@perl.org.
See golf thread.
If the alien golfers take up my challenge, it will be significantly shortened.
